4c886d613d Detect byte-swapped AC-3 and support decoding it directly. 
This allows the AC-3 decoder to be used directly with RealMedia
decoders that unlike the libavformat one do not byte-swap automatically.
Since the new code is only used in case we would fail directly otherwise
there should be no risk for regressions.

323e6fead0 ac3enc: do not right-shift fixed-point coefficients in the final MDCT stage. 
This increases the accuracy of coefficients, leading to improved quality.
Rescaling of the coefficients to full 25-bit accuracy is done rather than
offsetting the exponent values. This requires coefficient scaling to be done
before determining the rematrixing strategy. Also, the rematrixing strategy
calculation must use 64-bit math to prevent overflow due to the higher
precision coefficients.

a58bcb40b1 vmdaudio: fix raw_block_size calculation. 
The size should depend on the output sample size, not the internal bit depth.

381efba0ec ppc: fix vc1 inverse transform, unbreak build 
GCC 4.3 and later are more particular about signedness matching

f8bed30d8b VC1: merge idct8x8, coeff adjustments and put_pixels. 
Merging these functions allows merging some loops, which makes the
results (particularly after SIMD optimizations) much faster.
